1、Ceasing to Wear Ties
It's useless. It's dirty. It spreads disease. That's why the British Medical Association in the UK recently called for hospital doctors to stop wearing ties.
That leads to another question. Why does anyone wear a tie? Ties serve no purpose. They do not cover any part of your body and keep you warm. They always seem to get covered in food stains. Perhaps that is the purpose of the tie. It lets everyone know what you just ate.
Ties have an odd history. Soldiers from Croatia, in Eastern Europe, served as mercenaries (雇佣军) in various conflicts in the 17th century. They were identified by brightly colored pieces of silk worn around the neck. Known as cravats(围巾), these became a popular fashion item in France and eventually evolved into the tie.
It's an interesting story, but it doesn't tell us why men want to put useless pieces of cloth or silk around their necks. The answer seems to be about identification(身份证明 ). In the 19th-century Britain, ties were used by universities, military regiments (团), sports clubs, schools and gentleman's clubs. Each tie was in a particular set of colors which identified the wearer as a member of that organization. Wearing ties was also the mark of Britain's most powerful classes. That made the tie itself a symbol of power and respect. And that led it to be adopted by a much larger class-the business class.
You cannot wear a tie if you work with machinery, so wearing a tie became a sign that you were a man who used his brain to make a living, rather than his hands. It showed you were serious. It showed you were a professional. It meant that everyone who wanted a job in business had to wear one. It was just impossible to take seriously a man who did not wear a piece of colored silk around his neck. This is how millions of people came to wear ties across the world.
Is there a future for ties? The signs are not promising. Many political leaders, including British Prime Minister Tony Blair, now go without ties.

3、Fermi Problem
On a Monday morning in July, the world's first atom bomb exploded in the New Mexico desert, Forty seconds later, the shook waves reached the base camp where the Italian-American physicist Enrico Fezmi and his team stood. After a mental calculation, Fermi announced to his team that the bomb's energy had equated 10,000 tons of TNT. The bomb team was impressed, but not surprised. Fermi's genius was known throughout the scientific world. In 1938 he had won a Nobel Prize. Four years later he produced the first nuclear chain reaction, leading us into the nuclear age. Since Fermi's death in 1954, no physicist has been at once a master experimentalist and a leading theoretician.
Like all virtuosos (大师), Fermi had a distinctive style. He preferred the most direct route to an answer. He was very good at dividing difficult problems into small, manageable bits talent we all can use in our daily lives.
To develop this talent in his students, Fermi would suggest a type of question now known as a Fermi problem. Upon first hearing one of these, you haven't the remotest notion of the answer, and you feel certain that too little information had been given to solve it, Yet when the problem is broken into sub-problems, each answerable without the help of expert. s or books, you can come close to the exact solution.
Suppose you want to determine Earth's circumference without looking it up. Everyone knows that New York and Los Angeles are about 3,000 miles apart and that the time difference between them is three hours. Three hours is one-eighth of a day, and a day is the time it takes the planet to complete one rotation, so its circumference must be eight times 3000 0r 24000 miles. This answer differs from the true value, 24,902. 45 miles, by less than four percent.
Ultimately the value of dealing with everyday problems the way Fermi did lies in the rewards of making independent discoveries and inventions. It doesn't matter whether the discovery is as important as determining the power of an atom or as small as measuring the distance between New York and Los Angeles. Looking up the answer, or letting someone else find it deprives you of the pleasure and pride that accompany creativity, and deprives you of an experience that builds up self-confide. Thus, approaching personal dilemmas as Fermi problems can become a habit that enriches your life.
Fermi, an experimentalist as well as a theoretician, won a Nobel Prize for producing the first nuclear chain reaction in the world.
【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:文章第1段中提到Fermi在1938年获诺贝尔奖，四年以后才成功地实现了核连锁反应，所以题干的说法是错误的。

4、Operatunity
1. Operatunity is a TV talent show for amateur opera singers, The winners get the chance to sing with the English National Opera. When two housewives, Denise Leigh and Jane Gilchrist won in 2002, their lives changed forever, As they sang Verdi's Rigoletto at the Coliseum (音乐厅) in Rome, they were transformed from working mothers into opera celebrities (名人).
2. "I live in the village I was born in," says Denise, who is blind. "Lots of my neighbours are family, and my life is all about my three children. Jane, who worked as a cleaner and a shop assistant, was in a similar situation." She says. All I had to look forward to was seeing my four children grow up, and I love them, but ... you know there must be more things than life. Winning Operatunity has opened up avenues I never knew existed."
3. "Last year was amazing," Denise continues, "Last month was Paris, before that we were recording at Abbey Road, in London, and recently we had our album launch at the Royal Opera House" "We've been treated like princesses," laughs Jane, "... champagne, chocolates, five - star hotels ..."
4. But it wasn't all so easy. For Denise, the worst part was waiting at the beginning. "After I'd sent in my application form I worried for a month, Then I had to wait ten days after my first audition (试唱). That was awful." Even when they won the competition they were allowed to tell their close family but they weren't allowed to tell anyone else until later. Denise and Jane also found the travelling is difficult. They couldn’t take their children with them while they were away singing, so they had to organise childcare. However, there's been no problem with the physical side of singing: "We didn't have to worry about that as we've had lots of help and wonderful voice training." says Jane. They also had to learn to deal with the media." The kids loved the fact that they could stay up and watch us on TV, but I just couldn't understand why some newspapers were more interested in the fact I divorced at 21, rather than the fact I had just sung at the Coliseum, says Denise.
